| 摘 要： | 详细地研究了在4.0 GPa下，晶化时间为60 min，由非晶态玻璃转化成透辉石翡翠的晶化过程中，温度参数对人工透辉石翡翠的硬度和结晶度的影响。要使合成的透辉石翡翠的硬度达到天然翡翠的硬度，并且非晶态玻璃相全部结晶成透辉石翡翠，晶化温度不能低于1 400 ℃。此外，利用SEM研究了透辉石翡翠的晶体生长情况和晶粒编织情况，并就其成核与生长进行了讨论。本实验发现高温有利于透辉石翡翠形成均质结构，晶粒纤维更有序、粗壮、编织紧密。

| Abstract: | The effects of the crystalline temperature on the hardness and crystalline degree of synthetic diopside-jadeite were studied in this paper. Diopside-jadeite jewelry synthesized from glass with stoichiometry of 0.4CaMgSi2O6-0.6NaAlSi2O6 was obtained under 4.0 GPa, at the different temperatures from 900~1 900 ℃ and for 60 min. Two different hardness of the same piece of diopside-jadeite synthesized below 1 400 ℃ was caused by either the non-crystalline phase or its heterogeneous structure. The crystal growth and fibre construction of diopside-jadeite were studied by SEM at elevated temperature. The observed result reveals that the increasing temperature elevation is favorable to the formation of high quality diopside-jadeite jewelry that has longer, thicker, and more ordered crystal fibers. Microstructure of diopside-jadeite synthesized at higher temperature (>1 450 ℃) is much similar to that of the natural one. |
